Calories burned calculator

Want to know how many calories you burn running, cycling, swimming or doing other activities? This calculator uses MET (Metabolic Equivalent of Task) values from the Compendium of Physical Activities to estimate energy expenditure based on your body weight and exercise duration. Simply choose the activity, enter your weight and duration — get the result instantly.

How the calculator works

The calculator uses the formula: Calories = MET × body weight (kg) × time (h). MET (Metabolic Equivalent of Task) measures exercise intensity. 1 MET = rest. Higher MET = more calories burned. Example MET values: - Walking (4-5 km/h): 3.5 - Running (around 8 km/h): 9.0 - Cycling (moderate): 7.5 - Swimming: 8.0 - Aerobics: 6.5 - Weight training (general): 5.0 - Yoga: 2.5 - Football/soccer: 10.0 The result is an estimate — actual calories burned vary with intensity, gender, age and fitness level.

Example: running 60 minutes, weight 75 kg

Running (MET = 9.0) for 60 minutes at 75 kg: 9.0 × 75 × 1 h = 675 kcal. The same person walking (MET = 3.5) for one hour burns only 262.5 kcal — so running is about 2.5× more efficient for calorie burning.

Frequently asked questions

How are calories burned during exercise calculated?

Calories burned = MET × body weight (kg) × time (h). MET (Metabolic Equivalent of Task) measures activity intensity — the higher the MET, the more calories burned per unit of time.

How many calories does an hour of running burn?

At 75 kg and average running pace (MET=9): 9 × 75 × 1 = 675 kcal. A heavier runner or faster pace gives a higher result.

Which activity burns the most calories?

Football/soccer (MET=10) and running (MET=9) have the highest calorie burn. Yoga (MET=2.5) and walking (MET=3.5) burn significantly less.

How many calories does swimming burn per hour?

Swimming has MET=8.0. At 75 kg for one hour you burn around 600 kcal — depending on stroke and intensity.

Does the calculator include resting metabolism (BMR)?

No — it calculates only calories burned during the activity itself. Total daily energy expenditure (TDEE) includes BMR and is higher.

What is the MET index?

MET (Metabolic Equivalent of Task) expresses how many times an activity increases energy expenditure compared to rest. Rest = 1 MET. Values come from the Ainsworth Compendium of Physical Activities.

Indicative result

The result is an estimate. Actual calorie expenditure depends on individual metabolism, gender, age, intensity and fitness level. Not a substitute for dietary or medical advice.
